Description

Technical Field

[0001] This invention relates to an extraction device, and more particularly to an extraction device and method for extracting the traditional Chinese medicine *Achyranthes bidentata*. Background Technology

[0002] Maple is a shrub belonging to the genus Maple in the family Mauraceae. The bark, leaves, kernels, and fruits of Maple contain a variety of trace chemical elements and have anti-inflammatory, antispasmodic, anti-gastric ulcer, and anti-tumor effects. There are many ways to extract products from Maple, among which soaking and boiling is the most common. In the soaking and boiling process, the medicine is usually directly put into a tank and heated for processing.

[0003] For example, Chinese Patent Publication No. CN222468113U discloses an extraction tank for extracting the traditional Chinese medicine *Achyranthes bidentata*, which relates to the field of drug preparation equipment technology. The tank includes a base, a tank body mounted on top of the base, and inlet and outlet water pipes respectively inserted into the side walls of the tank body. A mounting groove is formed on the top of the tank body, and a fixing seat is installed within the mounting groove. A rectangular frame is mounted on the bottom surface of the fixing seat, and a lifting assembly is installed below the rectangular frame inside the tank. This extraction tank has a novel overall design and simple structure. The lifting assembly design allows for better release of the medicinal properties, resulting in higher overall extraction efficiency. However, this patent has the following problems: First, the method of reciprocatingly squeezing the drug in the rectangular frame can further squeeze out the liquid drug contained in the drug, but it will cause the drug to be tightly stacked and compressed together, which will prevent the liquid drug from effectively precipitating into the drug, resulting in insufficient dissolution of active ingredients and low raw material utilization. Secondly, using a simple simultaneous influent and effluent method results in a shorter contact time between the drug and the drug solution. To ensure the extraction of active ingredients from the drug, a large amount of drug solution is required for precipitation, leading to a high solvent consumption problem. Summary of the Invention

[0004] The purpose of this invention is to provide an extraction device and extraction method for extracting the traditional Chinese medicine *Achyranthes bidentata*, in order to solve the existing problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an extraction device for extracting the traditional Chinese medicine *Achyranthes bidentata*, comprising a base, on which a tank is fixedly connected, and further comprising: An inner extraction tube is installed at an incline within the tank, with its upper end extending out of the tank. A filter screen is embedded in the outer wall of the inner extraction tube, and a liquid inlet delivery pipe is fixedly connected inside the inner extraction tube. Several anti-clogging nozzles are embedded in the outer wall of the liquid inlet delivery pipe. The solution delivery mechanism includes a pump and an input pipe. One end of the input pipe is fixedly connected to the inlet delivery pipe. The pump is fixedly installed at the bottom of the tank. A return pipe is fixedly connected to the delivery end of the pump. A three-way solenoid valve is connected to the other end of the return pipe. The output end of the input flange is divided into two ends, A and B. End A is connected to the input pipe through a return pipe, and end B is connected to a discharge flange through a pipe.

[0006] Preferably, an observation window is embedded in the front of the tank.

[0007] Preferably, a control interface panel is fixedly connected to one side of the outer wall of the tank.

[0008] Preferably, the outer wall of the upper end of the extraction inner tube is provided with a threaded groove, and a sealing cap is threaded onto the threaded groove.

[0009] Preferably, the extraction inner tube is slidably equipped with a lower scraper ring and a gravity pressure ring, and both the lower scraper ring and the gravity pressure ring have clearance through holes at their centers, which are slidably engaged with the liquid inlet delivery pipe.

[0010] Preferably, a connecting rod is fixedly connected to the upper part of the lower scraper ring, and a handle is fixedly connected to the upper end of the connecting rod.

[0011] Preferably, the gravity pressure ring has an avoidance sliding hole, which slides in conjunction with the connecting rod.

[0012] Preferably, a one-way valve is fixedly connected to the other end of the input pipe, and an input flange is fixedly connected to the other end of the one-way valve.

[0013] An extraction method for extracting the traditional Chinese medicine *Acer buergerianum*: The drug is placed inside the extraction inner tube, with the inlet delivery pipe located in the middle of the extraction inner tube. At this time, the drug will surround the inlet delivery pipe. Using a solution delivery mechanism connected to an external solution pumping mechanism, the solution is delivered into the inlet delivery pipe. Using an anti-clogging nozzle, the solution can be delivered into the extraction inner tube, allowing the solution to come into contact with the drug solution, continuously precipitating the active substances inside the drug. Subsequently, the solution will drip to the bottom of the tank. The pump is started to pump the solution inside the tank to the discharge flange. As the content of active substances inside the drug decreases, the amount of active substances precipitated in the solution gradually decreases. The three-way solenoid valve is activated to connect the input end and end A, and then the solution will be delivered to the input pipeline for recirculation. Multiple cycles are used to further precipitate the active substances in the drug.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. By activating the three-way solenoid valve and connecting its input end to end B, the solution will be transported to the input pipeline for recirculation. Multiple cycles further precipitate the active substances in the drug. The multiple cycles increase the contact time between the drug and the solution, increase the concentration of the active substances precipitated in the solution, and effectively reduce the amount of solution used.

[0015] 2. The liquid inlet delivery pipe is centrally fixed inside the extraction inner tube. The drug added to the extraction inner tube will surround the liquid inlet delivery pipe. The solution is pumped into the extraction inner tube using an anti-clogging nozzle, which can directly pump the solution to the center of the drug. The solution will overflow from the center of the drug, effectively avoiding the problem of the drug being compacted and stacked together, which would prevent the solution from fully contacting the drug and effectively precipitating the active substances inside the drug.

[0016] 3. The handle allows the operator to easily pull the connecting rod, which in turn moves the lower scraper ring, allowing it to move out of the extraction inner tube. The lower scraper ring can also remove drug residues from inside the extraction inner tube, making it easier to clean and remove the drug residues later. Attached Figure Description

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] like Figure 1-6 As shown, the present invention has the following specific embodiments.

[0021] Example 1 An extraction apparatus and method for extracting the traditional Chinese medicine *Achyranthes bidentata*, comprising a base 1, a tank 101 fixedly connected to the base 1, and further comprising: The inner tube 3 is inclined and fixedly installed inside the tank 101, and the upper end of the inner tube 3 extends out of the tank 101. A filter screen 301 is embedded in the outer wall of the inner tube 3. A liquid inlet conveying pipe 4 is fixedly connected inside the inner tube 3. Several anti-clogging nozzles 401 are embedded in the outer wall of the liquid inlet conveying pipe 4. The solution conveying mechanism includes a pump 7 and an input pipe 8. One end of the input pipe 8 is fixedly connected to the liquid inlet conveying pipe 4. The pump 7 is fixedly installed at the bottom of the tank 101. The pump 7 is connected to a return pipe 701 at the conveying end. The other end of the return pipe 701 is connected to a three-way solenoid valve 702. The output end of the input flange 802 is divided into two ends, A and B. End A is connected to the input pipe 8 through a return pipe 703, and end B is connected to a discharge flange 704 through a pipe.

[0022] In this embodiment, by tilting and fixing the inner extraction tube 3 inside the tank 101, the drug, after being put into the inner extraction tube 3, will slide tilted down to the bottom of the inner extraction tube 3. At the same time, the liquid inlet delivery pipe 4 is centrally fixed inside the inner extraction tube 3. The drug added into the inner extraction tube 3 will surround the liquid inlet delivery pipe 4. The solution delivery mechanism will deliver the solution into the liquid inlet delivery pipe 4. The anti-clogging nozzle 401 will pump the solution into the inner extraction tube 3, directly pumping the solution to the center of the drug. The solution will overflow from the center of the drug, and then be filtered through the filter screen 301 and drip into the tank 101. The pump is then started. 7. The solution can be pumped to the three-way solenoid valve 702. Activating the three-way solenoid valve 702 connects its input end to end B. The three-way solenoid valve 702 is used to transport the solution to the discharge flange 704, thereby discharging the solution from the device. As the content of active substances inside the drug decreases, the amount of active substances precipitated in the solution gradually decreases. Activating the three-way solenoid valve 702 connects the input end to end A, and the solution is then transported to the input pipe 8 for recirculation. Multiple cycles are used to further precipitate the active substances in the drug. Multiple cycles increase the contact time between the drug and the solution, increasing the concentration of active substances precipitated in the solution and effectively reducing the amount of solution used.

[0023] Example 2 An observation window 102 is embedded in the front of the tank body 101. A control interface panel 2 is fixed to the outer wall of one side of the tank body 101. A threaded groove is opened on the outer wall of the upper end of the extraction inner tube 3. A sealing cap 302 is threaded on the threaded groove. A lower scraper ring 5 and a gravity pressure ring 6 are slidably installed on the extraction inner tube 3. Both the lower scraper ring 5 and the gravity pressure ring 6 have clearance through holes at their centers. The clearance through holes are slidably engaged with the liquid inlet delivery pipe 4. A connecting rod 501 is fixed to the upper part of the lower scraper ring 5. A handle 502 is fixed to the upper end of the connecting rod 501.

[0024] In this embodiment, the precipitation of the solution inside the tank 101 can be observed through the observation window 102. The control panel 2 allows for simple human-machine interaction between the device and the operator, enabling control of the three-way solenoid valve 702 and the pump 7 to start and stop. The sealing cap 302 is screwed onto the upper end of the extraction inner tube 3, sealing the upper end of the extraction inner tube 3. The lower scraping ring 5 is located at the bottom of the extraction inner tube 3. After the drug is filled into the extraction inner tube 3, the gravity pressure ring 6 is slidably installed on each part of the extraction inner tube 3. Utilizing the gravity of the gravity pressure ring 6, the precipitation can be achieved using gravity. The pressure ring 6 squeezes the internal drug to prevent the drug from bulging in the solution, which would result in a large amount of solution in the drug. The sliding fit between the connecting rod 501 and 602 can prevent the connecting rod 501 from interfering with the gravity pressure ring 6 and affecting the normal falling of the gravity pressure ring 6. The handle 502 makes it easy for the operator to pull the connecting rod 501. The connecting rod 501 can drive the lower scraper ring 5 to move, so that the lower scraper ring 5 is removed from the inside of the extraction inner tube 3. The lower scraper ring 5 fits between the extraction inner tube 3 and the liquid delivery tube 4, and can be used to remove all the internal drug residue.

[0025] Example 3 The gravity pressure ring 6 has an avoidance sliding hole 601 inside, which slides with the connecting rod 501. The other end of the input pipe 8 is fixedly connected to a one-way valve 801, and the other end of the one-way valve 801 is fixedly connected to an input flange 802.

[0026] In this embodiment, by avoiding the sliding fit between the sliding hole 601 and the connecting rod 501, the interference of the connecting rod 501 with the sliding of the gravity pressure ring 6 can be avoided. By using the one-way valve 801 connected in series between the input pipe 8 and the input flange 802, the solution flows back into the input pipe 8, causing the solution to flow back into the input flange 802, which in turn causes the solution to flow back to the external pumping device.

[0027] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
